Abstract-Within the United Kingdom a significant portion of the energy consumed each year is done so through industry. It is therefore desirable to take measures that reduce this consumption. A process common to all manufacturing sectors is that of packaging, and this research focused on identifying, quantifying and reducing the environmental impact of one such system. It finally took the form of an abridged life cycle assessment focusing on the manufacturing and assembly stage of a packaging systems life. Two separate studies were conducted to evaluate the performance of specific tools for such environmental studies. Where, the total embodied energy and carbon of each sub-assembly of the systems was calculated and their contribution to the whole machine established. These were further broken down into material production and machine processes in order to establish where the major impacts were and potential areas for redesign. Both approaches were found to be resource hungry in their application, an output that may restrict their application in the type of company that operate in this domain. A surprising finding was that producing a design with lower environmental impact could be less expensive.
This research is aimed at designing a wastewater transmission system from storage to treatment and, eventually to storage in an elevated steel tank. The work includes the design of a 750,000-litre capacity underground concrete reservoir and a 125,000-litre capacity elevated steel tank. For the transmission design, field activities involved the use of Magellan eXplorist 350H North America G.P.S. and Google Earth to determine coordinates of different points in a selected private university campus, southwest Nigeria as well as the lowest and the highest elevation points. The highest point in the university was located at the postgraduate hall of residence, and the lowest point was located at the schools constructed wetland within the campus. WaterCAD was used to design the flow path network, while the water storage design software used for this project are StaadPro.V8i, Orion 18, and AutoCAD 2013. StaadPro.V8i was employed for the analysis and design of the underground storage facility and the elevated steel tank, while the Orion software was utilized for concrete design and detailing of the underground storage facility. The results from all the design applications were exported to the AutoCAD environment for editing and proper scaling. This study has revealed that the construction of a 750 m3 underground storage tank would be highly efficient and economical when compared to a smaller tank. Also, both the hydrostatic forces acting internally within the underground tank and active and passive pressure acting externally toward the wall has shown to possess zero impact on the shear wall.
